Frequently Asked Questions
Why would I need an image under 20KB?
20KB is one of the smallest file-size ceilings used by online forms, almost always for a scanned signature rather than a full photo — most exam and banking portals cap a signature upload at 10-20KB specifically because it's a small, simple image with little detail to preserve.
Will compressing to 20KB make my signature unreadable?
A signature is mostly flat background with thin dark strokes, so it compresses far more cleanly than a photo at the same KB target — this tool keeps the strokes legible by searching for the highest JPEG quality that still fits under 20KB, rather than applying one fixed low-quality setting to everything.
What if my file is far larger than 20KB, like a phone photo of my signature?
That's normal and still works — upload it as-is. The tool scales and compresses it to reach the target; if you need an exact pixel size too (not just the KB ceiling), use the Exam Photo & Signature Resizer, which sets both at once.
Does this tool crop or resize my image, or only compress it?
This page only compresses — it keeps your image's original dimensions and just reduces the file size. For a fixed pixel size and KB range together (what most exam forms actually require), use the Exam Photo & Signature Resizer instead.
